The mum, who did not want to be named, added: “Parents are very upset. The school was closed today so people – like myself – have had to arrange last-minute childcare. They have grouped together to organise it.”

She added the school’s communication had been “brilliant” as every parent had been sent a text this morning – but added parents were in disbelief at what had happened.

“I’m furious beyond words. How can someone do that?” she said.

“I just cannot believe it. This is a residential street and there are houses directly opposite the school.”

She added Ashmead Primary had only completed building works onsite a few weeks ago.

Mr O’Flynn’s letter to parents thanked them for “kind words and actions to staff this morning, including drinks and baked goods.”

The school has said it will try to provide an update later today to confirm whether the school will be open tomorrow.
